Cyclic voltammetry experiments were conducted to investigate the first TCNQF0/- reduction processes occurring in solutions containing TCNQF and [Cu(MeCN)4]+ . The experiments showed that this process could be monitored without any interference from the second one. During this process, the formation of the solid CuTCNQF was recorded at a concentration of 8.0 mM for TCNQF and [Cu(MeCN)4]+. Noticeably, during the experiments, the generation of two different morphologies of CuTCNQF was observed via an additional irreversible CV wave. This material was successfully synthesized chemically and electrochemically and was characterized using the IR and Raman spectroscopy. CuTCNQF, unlike other fluoro derivatives, did not possess good catalytic activity on Fe3+/S2O82- redox reaction. The reaction rate with the presence of CuTCNQF was as slow as it was in the presence of CuTCNQ phase II.
